0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'SumoSelect'

I'm getting the above error message when trying to call the SumoSelect function against a select option element on an aspx page.

I have the following references in my web page:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js" type="text/javascript"></script>
<script src="jquery.sumoselect.js"  type="text/javascript"></script>
<link href="sumoselect.css" rel="stylesheet" />

With the files taken from: https://github.com/HemantNegi/jquery.sumoselect/zipball/master

At present I have only included the following in my project from the download:

1. jquery.sumoselect.js

2. sumoselect.css

My jQuery is correctly locating one of the element with:

<script type="text/javascript">
$(document).ready(function () {

  var elements = document.getElementsByTagName("*");

  for (i = 0; i < elements.length; i++) {
    element = elements[i];
    name = element.id;

    if (name.match(/FieldId_3/)) {
      $(element).SumoSelect();
    }
  }
});
</script>

However, when it reaches $(element).SumoSelect(); it produces the error "0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'SumoSelect'"

I'm very new to jQuery/Javascript, but have tried multiple permutations of trying to call this function and pass the object, however none have worked.

Any ideas to help me get it working?

I'll be grateful for any assistance.

first of all, you are using jQuery, why bother using Vanilla JavaScript to get DOM Elements, and iterate over all collection, only to get one element by its id? (id property should be unique in the document)

You can refactor your code and initialize your plugin only on the elements that meet the selector criteria:

$(document).ready(function () {
  $('#FieldId_3').SumoSelect();
});

If no elements meet the criteria, the plugin not will be initialized (safely), because jQuery return an empty like-array object.

And obviously, the element with id FieldId_3 must be a select element, as mentioned here: https://hemantnegi.github.io/jquery.sumoselect/
